Hi All,
When i am using rolling friction in my model, it is giving the following error;
ERROR: Fix wall/gran (id geometry): Unknown argument or wrong keyword order: 'rolling_friction' (../fix_wall_gran_base.h:96)
I have used the following statement in my input script
fix geometry all wall/gran model hertz tangential history mesh n_meshes 3 meshes cad1 cad2 cad3 rolling_friction cdt
Without rolling friction my script is working fine.
Any help will be much appreciated.
Thanks,
Narendra

try to put it after
try to put it after tangential history like this:
fix geometry all wall/gran model hertz tangential history rolling_friction cdt mesh n_meshes 3 meshes cad1 cad2 cad3
btw I would prefer the epsd or epsd2

wrong keyword order
If I remember correctly, it should be
fix geometry all wall/gran model hertz tangential history rolling_friction cdt mesh n_meshes 3 meshes cad1 cad2 cad3
see liggghts_3.X_tutorial.html in the doc folder for details

Thanks Joshuap and Daniel. It is working fine now. I have to read about epsd and epsd2.

ERROR IN PAIR_STYLE COMMAND
Hi All,
I am encountering the following error when I tried running my model
ERROR: Unknown argument or wrong keyword order: '2000.0'
the following is my input script
pair_style gran model hooke tangential history 2000.0 NULL 50.0 NULL 0.5 0
Need help in resolving it
Thanks,
Sureka

What are those numbers supposed to specify?
I don't see any options for the pair_style command that would take values of that kind (and LIGGGHTS doesn't find any either, as the error message suggests ...).
2000.0 NULL 50.0 NULL 0.5 0
What are those numbers supposed to specify? What do you intend to do there?
